3 Claims.

My invention is particularly applicable to metering pumps for dispensing gasolene and of the general character illustrated in Letters Patent of the United States No. 2,062,997, granted December 1, 1936 to me as assignor to John Wood Manufacturing Company, Inc., of Conshohocken, Pennsylvania.

Such computing registering mechanism includes means for indicating any selected price basis of the computation, means for indicating the volume of liquid dispensed at each operation, in gallons and fractions of a gallon; means for computing and registering the value of the volume dispensed at each dispensing operation in cents and fractions of a cent; and means for indicating such value. To insure correct computation it is necessary to have the mechanism manually set with reference to a selected price and to have both the volume and value indicators at their zero position before beginning any dispensing operation. Therefore, my present invention provides distinct but cooperative devices which may be termed locking means, for respectively insuring those three conditions of the mechanism before the operator can initiate any dispensing operation.

My invention includes the various novel features of construction, arrangement and method of operation hereinafter more definitely specified.

In the drawings: Fig. I is a plan view of the computing registering mechanism, having oppositely counterpart indicating means at both the left and right hand sides thereof, but omitting the rectangular face plates which have windows for displaying portions of the numbered indicating dials.

The liquid to be dispensed is conveniently stored in an underground tank from which it is elevated by the operation of a pump actuated by an electric motor. The liquid passes through the meter which includes a rotor which is turned by the passage of liquid from the pump, on its way to the dispensing hose. Said rotor makes one revolution for each gallon of liquid passed through said meter and is indicated at l in the drawings, and is the driving element for the computing registering mechanism with which it is detachably connected, conveniently, by the cross pin 2 on the shaft 3 shown in Fig. VI. Said shaft 3 is journaled in the bottom plate 4 of a rectangular housing in which the computing registering mechanism is mounted. Said shaft 3 carries the bevel driving gear 5 which is in mesh with the bevel gear 6 fixed on the tubular shaft 1 which is mounted to turn on the shaft 8 and carries the gear 9 in mesh with the gear ID on the shaft H. The arrangement is such that said shaft H is turned one revolution by each revolution of the meter shaft I, and consequently, said shaft ll makes one revolution for each gallon of liquid passed through the meter. Said shaft II carries and is keyed to a conical assemblage of thirty gears including opposite end gears I 3 and I respectively corresponding with the lowest and highest whole cents price of the liquid dispensed. In the embodiment of my invention illustrated, the price range of whole cents is from six cents to thirty-five cents per gallon.

iii)

Any one of said thirty gears may be selectively connected with the long pinion l5 by which the dials indicating the amount of sale, i. e., the value of the volume of liquid dispensed, are turned, as hereinafter described. Such selective connection is effected by the gear l6; which is carried by the rocker frame l1 so that it may be manually lifted to and from engagement with any selected gear in the conical series l3 to H. Said frame ll carries the blade l6 which extends as shown in Fig. IV into an arcuate slot in the interlocking sleeve 20, which latter controls the whole cents price display dial 2| shown at the left in Fig. II. The similar dial at the opposite side of the housing is marked 2 I in Figs. XI, XII, and XIII, and its hub is marked 24' in Figs. XI and XII. Said sleeve includes a series. of thirty such arcuate slots 22 in its periphery, of

which several are shown in Fig. VI. Said slots- 22 are so disposed in spaced relation circumferentially as to correspond with the whole cents of the price 6 to "35 on said dial and axially as to correspond with the gears of the conical series l3 to M inclusive.

As indicated in Fig. II, said dial 2| is in fact a ring having the diametrical cross plate 23 connecting it with its axial hub 24 and shaft 25; one end of said cross plate being between the numbers 6 and as shown in Fig. II, and the other end of said cross plate being between the numbers 20 and 21 upon the opposite side of dial 2|. Interruption of the regular spacing of said numbers on the dial 2| by the interposition of the ends of said plate 23 necessitates a corresponding irregularity in the circumferential spacing of said slots 22 in said sleeve 20. Said sleeve 20 is rigidly connected with the shaft 25 so that said sleeve may be manually turned to display a selected cents number of the price on said dial 2| at the price display window 21 in the face plate 28 shown in Fig. III and at the same time locate the proper slot in the series 22 in position to receive said blade I8 when said gear I6 is in mesh with the proper price gear of the series l3 to H on said shaft As shown in Fig. VI, gear I6 is in mesh with the gear |4, representing the displayed price of 35 cents per gallon as indicated in Figs. II and III.

Said sleeve 20 has at the right hand end there.- of in Fig. VI a ratchet head with thirty depressions in its circumference to selectively engage a spring pressed ball detent, to prevent accidental rotary displacement of said sleeve from any selected position to which it is manually adjusted. That construction is not shown in this case, for it is part of the subject matter of the copending application Serial No. 750,805 filed October 31, 1934, by Joseph C. Woodford for Letters Patent of the United States for Computing registering mechanism for liquid dispensing apparatus wherein the construction and arrangement of the price display mechanism including the interlocking sleeves such as 29 and 29 are claimed. Although the details of construction and arrangement of the price display mechanism are not herein claimed; it may be observed that the similar interlocking sleeve 29 has twelve arcuate slots 30 indicated in Fig. VI and controls the fractional cent price display dial 3| indicated in Fig. 11. Said dial 3| is mounted to turn freely on the left hand end of said shaft 25 which, as above noted, is rigidly mounted in said sleeve 20. The similar dial at the opposite side of the housing is marked 3| in Figs. XI and XII. As

indicated in Fig. II, said dial 3| has a circular series of numerals thereon indicating fractions of a cent for display through said window 21. As

indicated inFigs. II and III, the fraction display Said slots 30 in the locking sleeve 29' are adapted to receive the blade 3|, indicated in Fig. VI, which is prevented from axial movement in the housing of which said bottom plate 4 is a part. The shaft 32 is the pivot of the rocker frame 33 which carries the selector gear 34, so that the latter may be manually lifted and slid axially by tilting and axially moving said frame 33 to present said gear 34 in mesh with any two opposite gears in the two conical assemblages of gears 36 and 31, which are disposed for cooperation, to effect correct computation. Said shaft 32 cooperates with the detent lever 32', hereinafter described, to prevent operation of the computing registering mechanism unless and until said blade 3| is properly seated in any selected slot 30 in said locking sleeve 29.

As shown in Fig. VI; said assemblage of gears 36 is keyed in rigid connection with the sleeve 38 which is journaled on said shaft 8, as shown in Fig. VI, and is connected by a train of gearing so as to be driven by the shaft ll of the conical assemblage of gears l3, l4. That train includes the pinion on said shaft I I, indicated in dash and dot lines in Fig. IV, which pinion adjoins the intermediate housing frame plate 39 in which the left hand end of said shaft II is journaled, as shown in Fig. VI. Said pinion H is in mesh with the idle gear 4ll-journaled on the stationary stud 39' fixed in said frame 39. Said gear 4|) is in mesh with the gear 4|, shown in dash and dot lines in Fig. IV, which is rigidly connected with the sleeve 42, which is loosely journaled on the shaft 43, shown in dotted lines in Fig. IV. Said sleeve has at its left hand end, with reference to Fig. VI, the gear which is in mesh with the left hand end gear of the assemblage 36. Consequently, said assemblage 36 is thus turned by connection with the meter shaft I, by way of said shaft II, as shown in Figs. IV and VI.

Said assemblage of gears 31 is rigidly connected with the shaft 46, shown in dotted lines in Fig.

IV. Shaft 46 is journaled in the left hand end frame plate 41 and said intermediate frame plate 39, shown in Fig. VI. Said shaft 46 has formed thereon, adjoining said intermediate frame 39, the pinion 48, shown in Fig. VI and indicated in dash and dot lines in Fig. IV. Said pinion '48 is in mesh with the idle gear 49 which is journaled on the shaft 50 fixed in said intermediate frame 39, and said idle gear 49 engages the carrier gear 5| of the planetary gear train shown in section in Fig. VI.

Said planetary gear train includes the sun gear 52, which is fixed on the left hand shaft end of the long pinion l5 and is in mesh with the pair of diametrically opposite planetary gears 53, shown in dash and dot lines in Fig. IV, which are respectively journaled on studs 53' fixed in said carrier gear 5| at one end and in the ring 5| at the other end, as shown in Fig. VI. Said planetary gears 53 are in mesh with the respective gears of a diametrically opposite pair 54, shown in dot and dash lines in Fig. IV, and in section in Fig. VI, which are journaled on studs 54' fixed in said carrier gear 5| at their right hand ends shown in Fig. VI and which are fixed at their left hand ends in the carrier ring 5|.

As shown in Fig. VI, said planetary gears 54 are in mesh with'the second sun gear 56 which is'in coaxial relation with said long pinion I and first sun gear 52. As shown in Fig. VI, said sun gear 56 is rigidly connected with the shaft 56' which is journaled at its right hand end in said first sun gear 52 and at its left hand end in said housing end frame plate 41. Said shaft 56 has rigidly connected therewith the pinion 51 in mesh with the idle gear 58 journaled on the stud shaft 58 fixed in said housing frame plate 41. Said idle gear 58 has in unitary relation therewith the gear 80, shown in dash and dot lines in Fig. IV, and which is in mesh with the gear 6|,

indicated in dash and dot lines in Fig. IV, and V in section in Fig. VI. As shown in Fig. VI, said gear 8| is carried by the sleeve 82 journaled on the shaft 63 and which is rigidly connected with the cents dial 64, shown in elevation in Fig. II and in section in Fig. VI; said dial 64 is operatively connected with the oppositely counterpart dial 65 at the opposite, right hand, side of the mechanism shown in Fig. VI; so that the aggregate movements imparted to said pinion 51 as above described are manifested by rotation of said cents dials 64 and 85, and the number displayed at the right hand side of said dial 84 at its horizontal diameter, for instance "05 in Fig. II, is displayed at the window 68 in the face plate 28, as shown in Fig. III, and also at a corresponding window in the opposite face plate 28'.

Said gear BI is only frictionally engaged with said sleeve 62, by the spring 62', as shown in Fig. VI, in order to permit said cents dials 64 and 65 to be set back to their zero position as hereinafter described. The hub 64 of said cents dial84 and the hub 85' of said cents dial 65 are respectively provided with double gears 10 and 1|, shown in section in Fig. VI. Said gears are respectively in mesh with gears 12 and I3 which -are only indicated in dash and dot lines in Fig.

II, but which are precisely alike and rigidly connected with the shaft 14 indicated by dotted lines in Figs. I, II, and IV; which shaft is journaled in the three housing frame plates 39, 41, and 16, the latter being shown at the right hand side of Fig. VI. Said shaft 14 has the setback gear TI thereon, indicated by dash and dot lines in Fig. II, by which said dials 84 and 85 may be set back to zero position, as hereinafter described.

As shown in Fig. VI, said shaft 63 has rigidly connected with its opposite ends, oppositely counterpart dollars dials l8 and I8, both of which are shown in Fig. VI; the dial 18 being shown in Fig. II. Each of said dollars dials has a circular series of ten numbers thereon; viz., 1. to 9. and 0.. Said dollars dials are rigidly conheated with respective hubs I8 and I9, fixed on said shaft 83, as indicated in Fig. VI. Said shaft 83 is continually stressed by the helical spring 8| which encircles it, as shown in Fig. VI, which is anchored at its left hand end to the bracket 38 projecting from said intermediate frame plate 38, and is connected at its right hand end with the collar 8| fixed on said shaft 83; so that said spring continually tends to turn shaft 83 and dials l8 and 18 away from zero position. However, said spring 8| is controlled by an escapement including the ratchet wheel. 82, shown in section in Fig. VI, on the shaft 63 and the two pawls 83 and 83', also shown in section in said figure, having the bifurcated spring 84 continually stressing them into engagement with said ratchet. As shown in dotted lines in Fig. IV, said spring 84 is rigidly connected at its left hand end with the bracket 84' which is rigidly connected with said frame plate 16. Said pawls 83 and 88' are arranged to be tripped in succession by tappets 85 and 85'. shown in dotted lines in Fig. IV on said shaft 14. The effect of that arrangement is such that upon each rotation of said shaft 14, which corresponds with a complete revolution of said cents dials '84 and 55; said tappets release said shaft 88 and permit it to be turned by said spring 8| to the extent of the angle between adjoining dollar numbers on said dials 18 and 18 to register an additional dollar of value for each revolution of said cents dials 84 and 65. The dollar number thus advanced is displayed at said window 66 in the face plate 28, as shown in Fig. III, and also at the corresponding window in the opposite face plate 28'.

However, said dial structures are the subject matter of Letters Patent of the United States No. 2,022,632 granted November 26, 1935, to Joseph C. Woodford as assignor to John Wood Manufacturing Company, Inc., assignee of the present application, and are not herein claimed.

Said shaft 8 has fixed upon its respectively opposite ends the oppositely counterpart fractional gallon dials 81 and 88, both of which are shown in Fig. VI; the dial 81 being shown in Figs. II and IV. Each of said dials 81 and 88 has a circular series of ten numerals thereon, respectively "0/10 and 1/10 to "9/10, which latter represent tenths of a gallon. The mark 0/10 represents both zero and a whole gallon. Said dials are normally tumed'by frictional connection of said shaft 8 with the tubular shaft 1 shown in Fig. VI, and the gear 8 in mesh with the gear l8. Such connection is effected by the friction disk 88 fixed on said shaft 8, against which the gear 8 is pressed by the spring 88' encircling said shaft 8 and compressed between the right hand end of said tubular shaft 1 and the abutment collar 88 fixed on said shaft 8. Such frictional engagement is merely to permit said shaft 8 to be set back to present said dials 81 and 88 in zero position at the gallonage display window 8| in the face plate 28, shown in Fig. III, and the corresponding window in the opposite face plate 28, shown in Figs. II and IV; said face plates being precisely alike. During such setback movement, by means hereinafter described, said shaft 1 is held stationary by its connection with the shaft I of the meter .rotor which is then stationary. The whole galbeing retained in position abutting the frame plate 41 by means of the collar 36 which is pinned fast to said shaft 8. Said dials 82 and 83 have oppositely counterpart circular series of twenty numbers thereon from 1 to 19' and 0 representing twenty gallons, the mark 0 also representing the zero position of said dials. As said dials 82 and 83 are turned, the numbers thereon are respectively presented at said window 8| in the face plate 28 and at the corresponding window in said face plate 28. To turn them I provide said dials 82 and 93 with the respective gears 81 and 88 which are respectively in mesh with the gears 91' and 88' on the gallon dials connecting shaft 43, shown in dotted lines in Figs. II and IV. Said shaft 43 is journaled in the opposite end plates 41 and I of the housing shown in Fig. VI, which are rigidly connected with said bottom plate 4 and the top plate 4'.

Said tappet cam 94 has but one tooth, as shown in dotted lines in Fig. IV; and being fixed on said hub 88, as aforesaid of the frac tional gallon dials 81 and 88, makes one revolution for each gallon dispensed through the meter. Its single tooth is adapted to successively engage the ten teeth on the star wheel I00 shown in dotted lines in Fig. IV,which is on the right hand end of said shaft 43, with respect to Figs. I and V, and is conveniently in unitary relation with said gear 98'.

The relation of said tappet cam 94 and star wheel I00 is such that, at each revolution of said fractional gallon dials 81 and S8, said shaft 43 is turned of a revolution and turns said gal lon dials 92 and 93 V of a revolution to register and indicate dispensation of a gallon. Said dials 92 and 93 are detained in each position to which they are thus shifted, by any convenient detent means, forming no part of the present invention.

As shown in Fig. VI; said shaft 63 has fixed thereon the pinion IOI in mesh with the sectoral gear IOI' which is free to turn on said shaft I4, as shown in dotted lines in Fig. I and in .dash and dot lines in Fig. 11. When said dollar dials l8 and I9 are displaced from their initial position, by a dispensing operation; they are set back to zero by means of the pick-up, or plunger, pin I02 and the cam I02, which latter is pinned fast on the shaft 63 and is positioned in the recess in the enlarged head 62 of the sleeve 62, as shown in Figs. X and VI. As shown in Figs. X and VI, said pickup pin I02 is free to move through an opening in the head 62 of the sleeve 02, and said pickup pin is continually stressed toward the surface of the cam I02 by means of the leaf spring I02, which is fastened at one end to said head 62'.

The registering and indicating mechanism above described is arranged to be set back to zero position by clockwise rotation of the shaft I03 shown in Figs. 1, II, and IV, conveniently by a tubular key or crank slotted to fit over the end of said shaft I03 in engagement with the cross pin I03 fixed in said shaft. Said shaft I03 is journaled in the housing side plate I04 which is rigidly connected with said bottom plate 4 and top plate 4. As indicated in Figs. II and V; said shaft I03 has fixed thereon the bevel pinion I05 in mesh with the bevel gear I06, which latter is fixed on the shaft I0'I, journaled in said side plate I04.

As shown in Fig. V, said shaft I01 carries the ratchet clutch member I08 which is prevented from turning thereon "by the engagement of its slot I00 with the cross pin I09 fixed in said shaft, but said clutch member I08 is axially movable to and from engagement with the complementary clutch member IIO which is fixed on the shaft III journaled in said plate I04.

Said clutch member I08 is continually stressed toward the left in Fig. V, to its disengaged position against the rib I04 on said plate I04, by the tension spring II2 which extends from the stud II3, fixed in said plate I04, to the stud II4 projecting from the upper end of the yoke lever I I5 through the slot H5 in the bell crank clutch shifting lever II6. Said lever H5 is fulcrumed on the stud II6' fixed in the lower end of said lever H8, and the latter is fulcrurned on the stud H1 fixed in said plate I04. Said clutch member I08 is held in disengaged position during each dispensing operation by said tension spring H2.

The means for operating said clutch mechanism above described includes thev operating bar I24 which, as shown in Fig. V, is mounted to reciprocate vertically in bearings in the top and bottom members of the; box flange I25 on said housing plate I04. Said bar I24 is manually operative, by any convenient means, for instance, its lower end may be connected by the link I24 with a hook lever, which serves as a support for the liquid dispensing hose when the latter is in idle position; the arrangement being such that when the operator hangs the hose on said hook lever, which is not shown in the drawings, said operating bar I 24 is thrust upward to the position shown in full lines, from the position indicated by dash and dot lines in Fig. V, the latter position being the position of said bar during the dispensation of liquid and corresponding with the disengaged position of said clutch member I08. The detent latch II8 hangs on the pivot II9 fixed in the lever I20 which is also fulcrumed on said stud I I1 fixed in said housing plate I04. Said detent latch H8 is continually stressed towards the left in Fig. V by its spring 8' engaging the stud I2I fixed in said plate I04. When said clutch member I 08 is in disengaged position during each dispensing operation, the detent latch H8 is in the position shown in Fig. VIII, in which figure said latch H8 is shown pulled over the top of the shoulder I22 on the rib I04',by its spring II8. Said operating bar I24 has projections I24 and I24" extending from the left hand side thereof in Fig. V, for alternate engagement with the,

bottom and top of the right hand end of said clutch shifting lever US. In the position shown in Fig. V, said projection I24 has lifted said clutch shifting lever to the uppermost limit of its movement. Said stud II6' which is the fulcrum of the yoke lever II5 projects into the slot I26 in the link I2'I which is connected by the pivot I28 with said detent latch II8. Consequently, the upward movement of the right hand end of said clutch shifting lever IIG above described causes said link I2I to pull said detent latch II8 off of the shoulder I22 on. the rib I04, where it has been detained by its spring 8' while said clutch member I08 is in disengaged position. Said operating bar also carries the latch I29 which is pivotally connected with said bar by the bolt I30 and which normally hangs in the position shown in dash lines in Fig. V when said operating bar is in its lower position corresponding with the disengaged position of said clutch. In that position, said latch I29 rides over the upper left hand corner of the lug I25 which is fixed on said box flange I25. However, as said operating bar I24 moves to the position shown in full lines in Fig. V, the extension on the lower end of said latch I29 encounters the undersurface of said clutch shifting bell crank lever H6, and said latch I29 is knocked down to the position shown in Fig. V if dispensation has been effected by the apparatus; in which knocked down position it overhangs the top of the lug I25 which then prevents accidental downward movement of said operating bar I24 and consequent'release of said clutch member I08 until said latch I29 is released from its position overhanging said lug I25, by upward movement of the right hand end of said lever I20; consequent upon downward pressure of the lever I3I, the end of which overhangs the left hand end of said lever I20, as shown in Fig. V; said lever I3I being continually stressed downwardly by the spring I32 which extends therefrom to the bracket I32 on the frame plate 39, as shown in dotted lines in Fig. II. Said lever I3I is rigidly connected with the shaft I33, shown in dotted lines in Figs. I and II, which is journaled in bearings in the intermediate housing plate 39 and right hand end housing plate 16, shown in Fig. VI, but is behind the shaft 63 in that figure. Said shaft I33 has at the right hand end thereof with respect to Figs. I and VI, the lever arm I33, shown in dotted lines in Figs. I and II. As shown in Fig. 11, said lever arm I33 has connected with the pivot I34, the link I35 which has the slot I35 at its lower end connected with the pivot I36 on the lever I31, which is operated as hereinafter described.

Referring to Figs. II and V; said shaft I I I which carries the clutch member H0 is rigidly connected with the planetary gear carrier I38 comprising two rigidly connected parallel disks I38 in which are journaled pairs of intermeshed planetary gears I39 and I40. Said planetary gears I39, which are journaled in diametrically opposite positions in said carrier I38, as indicated in dash and dot lines in Fig. II; are in mesh with the sun gear I39 which is loosely journaled on said shaft III and extends through the left hand disk I38 of said carrier I38 to the rib I4I fixed on said housing plate I04. Said planetary gears I40, which are journaled in diametrically opposite positions in said carrier I38, as indicated in dash and dot lines in Fig. II, are in mesh with the other sun gear I40 which, as shown in Fig. V, is loosely journaled on said shaft III and extends through the right hand disk I38 of said carrier I38 and to the right hand vertical member of the box flange I25. Said sun gear I39 is in mesh with the gear I43 indicated by the dash "and dot lines in Fig. II. Said gear I 43 is loosely journaled on the shaft I43 which is supported in parallel flanges I45 projecting inwardly from the housing plate I04. Said sun gear I40 is in mesh with the gear I44 indicated in dash and dot lines in Fig. II. Said gear I 44 is loosely journaled on the shaft I 44 which is also supported in said parallel flanges I45.

As hereinafter described, said gear I 44 is used to set back to zero position th gallonage dials 81 and 92 shown in Fig. II, and said gear I43 is used to set back to zero position the dials 64 and 18 which respectively indicate the cents and dollars value of the liquid dispensed at any operation. The planetary gear connection between said shaft III and said gears I44 and I43 is to permit the gallonage dials 81 and 92 to stop at their respective zero positions while the value indicating dials 64 and 18 are turned further to reach their respective zero positions. That is to say, when the operator turns the set back shaft I03, the first effect thereof isto reset the gallonage dials 81 and 92 to zero position, whereupon, said dials being stopped in such zero position, by means hereinafter described, said gear I44 becomes stationary and further turning movement of said set back shaft I03 effects rotation of said gear I43 until the value indicating dials 64 and 18 are set back to their respective zero positions, whereupon, they are stopped by means hereinafter described, and the gear I43 becomes stationary and said shaft I03 cannot be further rotated. However, when that condition is reached, consequent upon the resetting to zero of all of the indicating dials; said detent latch I29, shown in Fig. V, (which is in effect a lock which, in the position there shown, prevents any dispensing operation), is automatically released from its locking position over the lug I25, by clockwise rotation upon its pivot bolt I30, shown in Fig. V, by upward movement of the right hand end of said lever I20; so that said operating bar I24 is freed to be manually lowered at the initiation of the next dispensing operation.

Said gear I 44, arranged to be driven as above described by the set back shaft I03, is continually in mesh with the gear I46, shown in dash and dot lines in Fig. II. Said gear I46 is journaled on said shaft 43 and in mesh with the gear I41 fixed on the shaft 8, as shown in section in Fig. VI and in dash and dot lines in Fig. II. As shown in dotted lines in Fig. II and in section in Fig. VI, said shaft 8 has fixed thereon the stop disk I48 having the stop notch I48 in its perimeter to engage the pendent right hand stop end of said lever I31, shown in dotted lines in Fig. II and in section in Fig. VI. Said lever I31 is fulcrumed on the stud I5I fixed in the housing plate 16, at the right hand end of Fig. VI and said lever I31 is continually stressed clockwise in Fig. II by the spring I52, shown in dotted lines in that figure. Said stop lever I31 is rigidly connected with the lever arm I 31, shown in dotted lines in Fig. 11 and in section in Fig. VI, which normally rides upon the circular portion of the circumference of the cam I53, also shown in dotted lines in Fig. II and in section in Fig. VI; which cam has the notch I53 into which the pendent end of said arm I 31' is permitted to drop and thereby release the stop lever I31 to drop into the notch I48 in time to. stop the rotation of said gallonage dials when they reach their zero position, by rotation of said shaft 8.

Said setback gear I43, shown in Fig. V, is continually in mesh with said set back gear 11 on the shaft 14, shown in dotted lines in Fig. I; so that after said setback gear I44 has stopped as above described, manual rotation of the setback shaft I03, as above described, reversely rotates said shaft 14, and the dials 18 and 19 are set back to zero position by means of the pickup pin I 02 and cam I02, as above described. Reverse rotation of said shaft 14 rewinds said spring 8|, shown in section in Fig. VI, encircling said shaft 63; said spring 8| being fully rewound to its initial tension when the value indicating dials have reached their zero position.

The setting back movement of said shaft 14, effective with respect to said value indicating dials 64, 65, 18, and 19, is finally stopped when they all reach their zero position, by the stop cam I55, which is fixed on the shaft 14, as shown in dotted lines in Figs. I and II; when the radial shoulder on said cam encounters the right hand end of the stop lever I56, shown in dotted lines in Fig. 11, which lever is fulcrumed on the stud I33. Said lever I56 is continually stressed clockwise in Fig. II, toward said cam I55, by the spring I56, shown in dotted lines in Figs. I and II.

However, if the value dispensed is less than a dollar, at any dispensing operation, the dollar dials 18 and 19 are not displaced from their zero position.

Stop means for the cents dials 64 and 65 in clude the stop cam I 51 which is rigidly connected with the cents dial 64, as shown in section in Fig. VI, and which has a single radial shoulder I51, shown in dotted lines in Fig. II, which encounters the left hand end of the stop lever I58 which is pivoted on the eccentric bolt I58 fixed in the frame plate 41, as indicated in dotted lines in Fig. 11'. The stop lever I66 may be adjusted with respect to said shoulder I 51', on the stop cam I61, by movement of said eccentric bolt I58. Moreover, as shown in dotted lines in Fig. II; said stop cam I61 has the cam shoulder I51" which, when said cents dials 64 and 66 and the cam I51 are turned to zero position, is presented at the right hand side of the stop roller I50 which is carried by the lever I6I fulcrumed on the stud I6I' on said housing frame member 41, as indicated in dotted lines in Fig. II, and continually stressed clockwise to press said roller I60 toward said cam I61, by the spring I62. The function of that stop mechanism is to eliminate overthrow, due to momentum in the resetting operation, past the zero indication of the cents dials 64 and 65, which is an inherent condition because of backlash and consequent lost motion between said gears 12 and 13 and said spring loaded take-up gears 10 and II.

However, I cooperatively connect said stop levers I63 and I66 by the link I63 which is pendent from the pivot I63 fixed in said stop lever I58, as indicated in dotted lines in Fig. II, and which carries at its lower end, the left hand end of the cross bar I63" (with reference to Fig. I) which is rigidly fixed in the right hand end of said stop lever I66 (with reference to Fig. II), with the effect that when said stop lever I56 is uplifted from its engagement with the stop cam I55, said stop lever I56 is uplifted from the stop cam I51 also.

As shown in Figs. XV and XVI: The right hand end of said cross bar I63" (with reference to Fig. I), extends into the cam slot MI" in the sectoral gear IOI', as indicated in dotted lines in Figs. I and II, which slot has a notch at its upper end, shown in Fig. II, into which said cross bar drops to permit the stop levers I50 and I50 to assume their lowermost position, in which'they cooperate with their respective stop cams I 55 and I51, as above described. Turning of said shaft 14 with stop cam I55 clockwise in Fig. II, consequent upon operation of said meter, lifts said cross bar I63" out of said notch in the slot IOI uplifts both stop levers I56 and I53 to idle position and holds them there, until said notch is again presented in the position shown in Fig. II, by manipulation of said setback shaft I03.

Moreover, if liquid is dispensed to a value of $1.00 or more, the end of said cross bar I63" which extends through said slot I 0|" in the sectoral gear IOI', as shown in dotted lines in Fig. I, and in full lines in Fig. XV, projects under the lug I3I' on said lever I3I so as to uphold the latter whenever said cross bar is upheld as above described. Furthermore, on said shaft 14 is secured the semi-circular cam surface I3l" concentric with the axis of said shaft 14 which also upholds said lever I3I during the major portion of the revolution of said shaft I4 in which said cam is in operative relation with said lever.

Therefore, it may be observed that said lever I3I may be upheld, in the position shown in Fig. V, by all or any of three different devices, all of which devices must release it as a consequence of the indicating dials reaching their respective zero positions, before the spring I32 of said lever I3I is permitted to pull it down to tilt the lever I20, shown in Fig. V, to release the latch I29 from its position shown in Fig.- V, and thus permit said operating bar I24 to be lowered at the initiation of a dispensing operation. Those three devices are, viz., first, the stop disk I43 with its associated cam I63 on said shaft 8; second, said cam i3l" on said shaft 14; and, third, the end of the cross bar I63" engaging the lug I ii of the lever I3I.

When said devices upholding said lever ill have released said lever to permit its downward movement; it is pulled downward by its spring I32, tilts the lever I to the extent indicated in Fig. VII, and thereby turns the latch I20 clockwise free of said lug I, shown in Figs. V, and VII, to thus free said operating bar I24 for downward movement by the operator to initiate a liquid dispensing operation.

Said setback gears I43 and I44 being continually in mesh, respectively with said setback gear 11 on the shaft 14 and the gear I46 journaled on the shaft 43, are, of course, continually turned by the operation of the computing registering mechanism when it is actuated by the meter driven shaft 3, shown at the bottom of Fig. VI; such movement being in the opposite direction to that in which said setback gears I43 and I44 are turned by manual rotation of the setback shaft I03; but, the clutch member I03 being disengaged from the clutch member IIO, shown in Fig. V, during such operation of the computing registering mechanism; rotation of either or both of said gears I43 and I44 then merely idly operates the differential gear mechanism with which they are connected, and idly turns said shaft III with the disconnected clutch member IIO thereon.

Referring to Fig. IX; said detent lever 32' is fulcrumed on the stud 41' fixed in said housing frame plate 41, shown at the left hand side of Fig. VI, and is provided with the spring 32" continually stressing said lever counter-clockwise to present its right hand end between teeth on the gear 12 on said shaft 14; so that, unless and until said detent lever 32' is depressed against the stress of its spring to remove said lever from engagement with said gear 12, the computing registering mechanism is prevented from turning. Such movement is effected by the turning movement of said shaft 32, which has a flattened portion which, when presented to said detent lever 32', permits it to be uplifted by its spring, but when said shaft is turned by the blade 3i to the position in which the latter is properly seated in any of the slots 30, the cylindrical portion of said shaft 32 depresses said detent lever 32' to its inoperative position and thus permits the computing registering mechanism to be then operated.

It may be observed that there are three distinct groups of means which cooperate to insure that the computing registering mechanism shall be in proper position and condition for correctly computing and registering, with reference to a predetermined price, the quantity of liquid dispensed and the value thereof, before any operation of said computing and registering mechanism. is permitted, to wit, first, the means including said detent lever 32' which insures that the computing registering mechanism is set to compute at some predetermined price; second: the means including the stop lever I31 and lever arm I31 which insure that the volume indicating dials shall be at their zero position before a dispensing operation is initiated, and, third, the means including the timing cam I3I" and lever I3I which insure that the value indicating dials shall be at their zero position before a dispensing operation is initiated. Although said three means are separate and distinct, they cooperate to insure that the computing registering mechanism shall not be operated unless and until each and every one of them has accomplished its purpose and separately releases said mechanism for operation. That is to say; the mechanism may be released by any one or two of said three detent devices without permitting operation of the computing registering mechanism until the third device has accomplished its function.

Therefore, I desire to claim the combination of said three devices in their cooperative relation with the computing registering mechanism. However, as far as I know, each of said devices has features of novelty per se which I desire to claim.

Therefore, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that var- I ious modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.

I claim:

1. In a registering mechanism; the combination with two dials each bearing a series of numbers beginning with zero; 01' means for advancing said dials independently of each other; means for resetting said dials to zero position despite any difierence in the extent of their advancement, including a train of differential gearing connecting said dials, and normally idle while said dials are being advanced; and means normally disengaged from said train of gearing, adapted to be moved into engagement therewith, for resetting said dials successively to zero position in accordance with their relative extent of advancement.

2. Apparatus as in claim 1; wherein each dial is provided with means for stopping its rotation when it is in zero position; so that said dials are thus stopped in succession upon resetting movement thereof, in accordance with their relative advancement from zero position.

3. Apparatus as in claim 1; wherein the resetting means is operatively connected with a sun gear of the diflerential gearing train.
